A REMOTE CCTV AND DISTRIBUTION AMPLIFIERS MONITORING AND CONTROL SYSTEM FOR VIDEO SIGNALS DISTRIBUTION IN THE CASE OF SWECOM PLC KUMBA

ABSTRACT

Remote CCTV cameras and Distribution Amp for monitoring and control system for video signals distribution plays a vital role in improving the quality of video signals distributed and to improve on the method control.

It will provide to the technicians vital information about the site and the status of the number of connections made in the network, thereby enabling them to be able to identify any unauthorized user in the network without their present at the site.

The distribution amplifier receives, boost up and distribute to many different output. CCTV (Close-Circuit Television) cameras are used for the surveillance of the site areas.

This method improves the connection efficiency of the site, the technicians and the customers

CHAPTER ONE

GENERAL INTRODUCTION

1.0 Introduction

The phenomenon of signals congestion has becoming predominant due to rapid increase in the number of cable line viewers in telecommunication.

Video signals become congested when too many users of coaxial cables are connected to a low power distribution Amplifier which cannot amplifies the video signals to supply them. The use of CCTV is introduced to control these connections.

In electronics, a distribution amplifier, or simply distribution amp or DA, is a device that accepts a single input signal and provides this same signal to multiple isolated outputs.

These devices allow a signal to be distributed to multiple destinations without ground loops or signal degradation.

They are used for a number of common engineering tasks, including multiple amplification, cable television, splitting monitor Automatic or Automation: Is the technology by which a process is performed with minimal human assistance.

Manual: It involves getting something done with the help of a human.

Signals: Are electrical impulse or radio wave transmitted or received mixes, and “tapping” a signal prior to sending it through effects units to preserve a “dry” signal for later experimentation.

CCTV video splitters and security camera amplifiers assist installers in running cable longer distances and sharing the video signal from a surveillance camera with multiple devices. CCTV Camera Pros sells video splitters and amps for analogue CCTV cameras and HD security cameras (HD-SDI, AHD, HD-TVI, HDCVI).

1.1 Background of the Study

The CCTV cameras were first utilizing the   United   State military in the 1940s. the close circuit cameras was set up during the testing of the V2 missile in order to safely monitor test.

By using these CCTV officials were able to monitor the test at close range without the danger, watching out for the defect and other problems that might have otherwise gone undetected.

In 1960s, officials in UK began installing the CCTV system in public places in monitoring crowd during rallies and appearance of public figures. 

Installing the CCTV became more popular, both in public places and retail stores as the technology develop.

Today in Britain, CCTV monitor roads, sidewalk and squares in the city centers, public retail station and bus, as well as retail shops and other businesses.

In 1996 the government spending on CCTV technology accounted for three quarters of prevention of crime budget in the UK.

In the United State, the first CCTV was set up in the public building in the 1969 in the New York municipal building. The practice quickly spread to other cities and was soon widely   implemented. Unlike UK CCTV in the United State was rarely used.

However, in the 1970sand 1980s, CCTV use became more common in established prone to security threat, like banks, convenience stores and gas stations.

The cameras were installed in the world trade center as a preventative after the terrorist attack in 1993.

By the mid-90s, ATMs were commonly equipped with the CCTV camera, and many retail stores used the CCTV cameras to prevent theft.

Personal use of the CCTV cameras has become widespread as technology becomes much more easer to acquire. Many utilize CCTV cameras in their homes to catch cheating and monitoring of their children in “Nanny cams”. Student behavior is a problem that cannot be regarded as trivial.

This problem of student bringing weapons to school is an issue that will not go away by its self. School children are harming each other   with regularity.

This problem is particularly acute and complicated by their connection to the prevalence of poverty, crime and despair. The installation of the surveillance system will help student to focus on their studies and not make them worry about outside violence.

Security technology and applications have both come a long way since their humble beginnings— which, surprisingly, date back all the way to WWII. In this timeline, we’ll take a look at some of the most significant milestones in CCTV history.

Streamlined Home Security through CCTV Technology and VCRs While the video cassette tape was invented in 1951; a commercial product didn’t reach the market until much later in 1969. This enabled building owners to record security feeds— which is a lot of steps for a process now streamlined by HD DVR security camera recorders.

However, cassette tapes weren’t the most advanced video feed recording method for long. During the 70s, VCRs replaced video cassettes as the simplest way to record and view video surveillance footage. And New York City was eager to take advantage of this technology to record and prevent crime, too. In the early 70s, they placed security cameras in problem areas throughout the city to begin tackling crime.

But the digital improvements didn’t end there. In the early 90s, manufacturers began using a technique called digital multiplexing. in related zones— and placed the feeds on a single monitor or TV.

Video surveillance cameras became a go-to source when law enforcement agencies investigated robberies, assaults, car crashes, and more.DVRs Provide a Convenient, Simple Recording Solution DVR recording technology made the recording process even more convenient by cutting out several steps.

Rather than using a multiplexer unit to compile several video feeds, DVRs did this automatically.

Not to mention, the ample recording space beat the minuscule storage on video tapes by a mile, removing the hassle of constantly changing tapes .Eventually, this technology allowed people to view video even from remote locations.

1.2 Statement of the problem

While at SWECOM the intern observed that video signals distribution through coaxial cables can only be check by field technicians while in the field.

In other words, the technicians need to go to the site to check the number of cables that are connected to the different splitter set in place .

When the number of cables connected are more that the require number, this means that unauthorized users have been connected, it may lead to low quality video images to customers and in turn affect the company’s income.

After some months the superiors of the company will have to go down to the field to check the number of customers who are connected to the distribution Amp.

 Base on the problem of customers complaining of receiving poor quality video images due to interaction from perpetrators, the observer decided to embark on this project.
